摘要
提出了全面考虑ＤＳＴ非自喷井测试周期的压力解释方法─—周期法，并用大量实例解释结果，将周期法与ＤＳＴ非自喷井解释模型的Ｃｏｒｒｅａ法、Ｐｅｒｅｓ法以及自喷井常规解释模型的霍纳法进行了对比，讨论了前测试周期及关井续流对解释结果的影响，指出常规解释模型有停于实际测试条件，周期法更能解释早期压力资料。
A new met hod with DST test cycles on a non flowing well is presented ,definedas“cyclemethod”,and is conipared with Correa method Peres method for DST interpretation modeland Horner method for conventional interpretation model.On the basis of large amount ofsuch data with cycle method,the effect of preceeding test cycle and shut-in afterflow on theinterpretation resuIts is discussed.It shows that the conventional method can not satisfy theactuaI testing condition。The cycle method has advantage of using early pressure data treat-ment.
